narran s'rains pagina@ @ENCE ROBERT K. Jaynes, Yor Jackson, i/iississirrijL I i RUNNING-GEAR;

'To all whom it may concern Beit knownl thatl, Roisiiur K. J AYNE, -a citizen of the United` States, residing atk Jacksoiuin the county of Hinds" and State of Mississippi, have inventedk certain.- new and useful Improve-ments in Running-Gears,

of v'which the followingfis a speciication.

rlhis invention relates to vehicles and'niorev particularly to newA and useful running gears for the same. l Ani object of the invention is the provision of running gears for various types of -vehicles, in which rollers are substituted for the ordinarywheels thus providing a greater supporting surface which 'will run smoothly over rough or uneven ground and which will have a tendency to smooth and pack rather than cut in or otherwisel mar ythe. surface of the highwavs over which lit travels as is the case with tue ordinary vehicle wheel.

Anotherv object of this invent-ion is the provision of running gears of this nature whiclimay be easily and conveniently turned so as to round corners or the like and one which owing to' its constructionwill eliminate the necessity of Macadamized highways throughout the country in that the greater surface ofthe wheels or rollers will allow them to pass freely and smoothly over dirt roads.

A. still further object of this invention is the provision of means to prevent mud or looseeartli from clinging to the wheels or rollers of the vehicle.

lVith the foregoing and other objects in view, this invention consists in such novelk features of construction, combination and arrangement of parts as will be hereinafterv more fully described, illustrated in the accompanying drawings and claimed.

ln describing this invention in detail reference will be had to the accompanying drawings wherein like characters of reference designate like or corresponding parts throughout the several views, and in which,

Figure l is a side elevation of the im proved running gear; Fig. 2 is a front view of the improved ruiming gear; Fig. 3 is a rear view of the running gear; and Fig. 4 is an inverted plan view of the running gear with the frame removed.

Referring more particularly to the drawings 1 designates the frame of the running gears of a vehicle which is'constructed in accordance with the shapes of the bodies of various types of vehicles and which has a `adjacent sides of the tworollers'?. 1

member 2 connected to itsrearnend in any-lf suitable manner. The member 2 is substantiallytheshape of an invertedlU;` Thetlvoyleg portions and l of the member 2..,ha-vebearingsy 5 formedupon .their lower .ends f in j specification of Letters raient. ptentedsept.' 8,' 1914, vAppiieeemi flied August is, i9i3.

which isjo-urnaled a'shaft 'or `axle 6. The j shaft or axlel hasrollersTmounted thereupon. .In 'the drawings twofr'ollers T are,V

shown mounted upon the axle 6l y.and are 465 also shown as spaced apart leaving a lshorts. v space between their( adjoining sides i butt.rv should it be desired a singleroller maybe: v mounted uponr the shaft @andv extend the" -entire distance across therear portiony of? the vehicle frame 1'.' Abrace which-hasv abearing 9 formed upon oneend thereof extends upwardly from the rear axle'yandl is bent at 10. v ,The .portion of the member z.. 8 extending forward 'from Ythe bending point j atcthe fifth wheel'. 11;y of thefvehicle. .The` rear .axle ,6 is j ournaled throughk the bearing 9 vand thebearing 9 is disposed between the kThe fifth wheel 11 which .is disposedupon.

the front portionk of they vehicle j frame 41 A i has a memberj12 which is kalso the shape of an inverted U connectedthereto.A "The sides 13 and le off the member 12 liaverbearingsl 15 and 16 formed upon their lower endsg.

in which is jo-urnale'd thev front axle 17 kof the vehicle. The front laxle lf? has 'rollers' '18 rotatably mounted thereupon. "Thefroll ers 18 are similarv in construction to the rollers 7 and these rollers Tand '518 are substituted for the usual type of vehicle wheel. A reach section 20 having. an arcu-y ate or semi-circular portion as shown, 'also naled. The reach section member 20 is constructed of bar steel having its upper Vand lower surfaces as well as its inner surface straightl so as to be e'fliciently and approximately anti-frictionallyl engaged by the rollers 22, 23 and 24;. The rollers 22," 28 and 24 are carried by arms l25 and 26 whichk der surface ofthe members Sandforms lan,l

auxiliary support for the same?SIT "has bearings 2ll formed upon itsy ends, in which bearings the frontaxle- 117 is jour-y ico 75 `10y is yparallel with theframe land abuts 1;] vthe under `surface of the same terminating;

By the provision of the semiciroula-r member 20 and the various rollers which are in `engagement therewith, a vehicle running `gear is Vprovided which may be easily,y

Iquickly and conveniently turned as the member '20 and the rollers form an auxiliary fifth wheel for lthe running gears and eni rables the front portion of the ruiming gear i to be turned l0 practically at right angles to the rear` portion. v- L f The front and rear axles 17 and 6 of the vehicle have arms50 rigidly mounted upon their outer ends.V

The arms 50 extend rear- 'waidly andv upwardly from the axles and have scraper blades y5l pivot'ally connected thereto as'at 52. The scraper blades 51 are pivotally connected to the arms 50 by means fof bolts which extend through the arms 50 4and' which have nuts 53 mounted upon their v`outer ends which" protrude `through the arms. vThese nuts form means for adjust ingthe scraper blades 51 in that they may .beloosened upon tliebolts permitting of the pivotal movement of the scraper blades soitliat the blades may be held in various adjusted positions relative to the surface ofitlie rollers. Thescraper blades 5l eXtend laterally acrossvthe vehicle, forming means for fp'reif'entingr the mud, dirt or the like from clinging to the Vsurface of the roller. 1f By pivotally connecting the scraper blades i Vlto the arms 50 the blades may be ad- Y vjusted so thatthey will engage the surface 'of the rollers orso-that they Will be spaced away from the rollers preventing their enegagementl therewith as is desired.

In practical fields certain minor features .i of" construction, combination and arrange- `ment of vparts may necessitate alterations to which'the patentes is entitled provided such alterations are comprehended within the scope oi' what is claimed. lWhat is claimed is:

l. In a vehicle running gear structure, a turnable front aXle, a

connected to the front axle, a 4second substantially horizontally disposed reach sec` tion, said second reach section connected to the rear axle and in supportingrelation with rear axle, traction members mounted onv said axles, a substanV tially horizontally disposed reach section thel first reach section, a frame-brace member connected to one of said axles and eX tendingupvvardly and over :the second reach section, and an upstanding support member aXle, traction p tion havin 0' an arcuate portion for the purpose speci 'ed, a second reach section, substantially yhorizontally disposed, said second reach section connected to the rear axle, said second reach section having an arm extend- .ing across the first reach section, a plurality of rollers on said arm, one of said rollers engaging the inner face of the first reach section and the other ofk said `rollers en` gaging the under face of the irst reach section for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
